Cisco Catalyst 3750-E Software

Cisco Catalyst 3750-E Series is available with either the IP Base or the IP Services feature set. The IP Base feature set includes advanced quality of service (QoS), a suite of security features, rate-limiting, access control lists, and basic static and Routing Information Protocol (RIP) routing capability. The IP Services feature set provides a richer set of enterprise-class features, including advanced hardware-based IP unicast and multicast routing-Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP), Protocol Independent Multicast (PIM), and IPv6 routing such as OSPFv3 and EIGRPv6.

Customers can transparently upgrade the software feature set in the Cisco Catalyst 3750-E Series Switches through Cisco IOS® Software Activation. Software activation authorizes and enables the Cisco IOS Software feature sets. A special file contained in the switch, called a license file, is examined by Cisco IOS Software when the switch is powered on. Based on the license's type, Cisco IOS Software activates the appropriate feature set. License types can be changed, or upgraded, to activate a different feature set. For detailed information about Software Activation, visit http://www.cisco.com/go/sa.

Investment Protection

The Cisco Catalyst 3750-E Series Switches are compatible with the Cisco Catalyst 3750 Series Switches, enabling customers to stack them together and thereby protect existing investment in the Cisco Catalyst 3750 Series Switches. The Cisco TwinGig Small Form-Factor Pluggable (SFP) converter module further protects customers' investment in Cisco Catalyst 3750-E Series Switches by enabling migration from Gigabit Ethernet to 10 Gigabit Ethernet uplinks, as business needs require, without having to upgrade the switches.

Cisco StackWise Plus Technology

Cisco StackWise Plus technology is built on the highly successful StackWise™ technology, which is a premium stacking architecture optimized for Gigabit Ethernet. StackWise technology was designed to respond to additions, deletions, and redeployment while maintaining constant performance. The stack behaves as a single switching unit that is managed by a master switch elected from one of the member switches. The master switch automatically creates and updates all the switching and optional routing tables. A working stack can accept new members or delete old ones without service interruption. StackWise creates a highly resilient single unified system of up to nine switches, providing simplified management using a single IP address, single telnet session, single command-line interface (CLI), auto-version checking, autoconfiguration, and more. StackWise Plus supports all the features of StackWise and provides backward compatibility with the existing Cisco Catalyst 3750 Series Switches while enhancing the throughput of the system up to 64 Gbps. StackWise Plus also enables local switching in Cisco Catalyst 3750-E Series Switches. Local switching packets coming into a port in the Cisco Catalyst 3750-E Series Switch destined for another port in the same switch do not have to traverse through the stack ring, thus increasing the forwarding capacity of the switch.

Cisco EnergyWise Technology

Cisco EnergyWise is an innovative architecture, added to the Cisco Catalyst 3750-E switches, promoting companywide sustainability by reducing energy consumption across an entire corporate infrastructure and affecting more than 50 percent of global greenhouse gas emissions created by worldwide building infrastructure, a much greater effect than the 2 percent generated by the IT industry. Cisco EnergyWise enables companies to measure the power consumption of network infrastructure and network-attached devices and manage power consumption with specific policies, reducing power consumption to realize increased cost savings, potentially affecting any powered device.

EnergyWise encompasses a highly intelligent network-based approach to communicate messages that measure and control energy between network devices and endpoints. The network discovers Cisco EnergyWise manageable devices, monitors their power consumption, and takes action based on business rules to reduce power consumption. EnergyWise uses a unique domain-naming system to query and summarize information from large sets of devices, making it simpler than traditional network management capabilities. Cisco EnergyWise's management interfaces allow facilities and network management applications to communicate with endpoints and each other using the network as a unifying fabric. The management interface uses standard SNMP or SSL to integrate Cisco and third-party management systems.

Cisco EnergyWise extends the network as a platform for power control plane for gathering, managing, and reducing power consumption of all devices, resulting in companywide optimized power delivery and reduced energy costs.

10 Gigabit Ethernet Uplinks and the Cisco TwinGig SFP Converter

The Cisco Catalyst 3750-E features wire-speed 10 Gigabit Ethernet uplink ports for high-bandwidth applications, relieving congestion and ensuring smooth delivery of data. The TwinGig SFP converter (see Figure 2) converts a 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet SFP ports. This way, customers can initially use the switch with Gigabit Ethernet uplinks and later implement 10 Gigabit Ethernet uplinks as business demands change, without having to upgrade the access layer.

Figure 2. Cisco TwinGig Adapter Converting 10 Gigabit Ethernet X2 Interface into Two Gigabit Ethernet SFP Interfaces

Modular Power Supplies

The Cisco Catalyst 3750-E Series Switches have one power supply slot and support the following power supplies. PoE switches require a PoE power supply. Data-only switches can operate with any of the power supplies.

• C3K-PWR-1150WAC: 1150WAC power supply with 800W PoE

• C3K-PWR-750WAC: 750WAC power supply for 24-port switch with 420W PoE

• C3K-PWR-265WAC: 265WAC power supply for 48-port or 24-port switch without PoE

• C3K-PWR-265WDC: 265WDC power supply for 48-port or 24-port switch without PoE

Maximum power availability for converged voice and data networks is attainable when a Cisco Catalyst 3750-E Series Switch is combined with the Cisco RPS 2300 Redundant Power System for transparent protection against internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power outages. Using the RPS 2300 to provide backup power, the Cisco Catalyst 3750-E Series Switch power supplies become hot swappable. Table 3 shows the power supply compatibility matrix.

Power over Ethernet

The Cisco Catalyst 3750-E Series can provide a lower total cost of ownership for deployments that incorporate Cisco IP phones, Cisco Aironet® wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE removes the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments. The Cisco Catalyst 3750-E 24-port PoE configurations can support 24 simultaneous full-powered PoE ports at 15.4W for full powered-device support. The Cisco Catalyst 3750-E 48-port PoE configurations can support 48 simultaneous full-powered PoE ports at 15.4W when using the optional 1150W power supply. Alternatively, for deployments that do not need full PoE on all ports, a smaller power supply can be used in conjunction with Cisco Catalyst Intelligent Power Management to support 24-port and 48-port PoE configurations.

In addition, Cisco Catalyst Intelligent Power Management supports Enhanced PoE where up to 20W of PoE can be delivered to each port. This capability enables support of PoE devices such as 802.11n wireless equipment where >15.4W of PoE is required.

Redundant Power System

The Cisco Catalyst 3750-E Series Switches support the new generation of Redundant Power Supply (RPS) 2300. The RPS 2300 increases availability in a converged data, voice, and video network by providing transparent power backup to two of six attached Cisco Catalyst 3750-E Series Switches at the same time. The failed power supply can be swapped out while the switch is being powered up by the RPS 2300.

Primary Features and Benefits

Ease of Use: Deployment

A working stack is self-managing and self-configuring. When switches are added or removed, the master switch automatically loads the Cisco IOS Software version running on the stack to the new switch, loads the global configuration parameters, and updates all the routing tables to reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.

The Cisco Catalyst 3750-E Series stacks up to nine switches as a single logical unit for a total of 468 Ethernet 10/100/1000 ports, 432 PoE 10/100/1000 ports, or 18 10 Gigabit Ethernet ports. Individual 10/100/1000 units can be joined in any combination to evolve with network needs.

Other ease of use features include but are not limited to:

• Smartports enable fast and easy configuration of Cisco recommended best practice security and QoS features, encapsulating years of Cisco networking expertise.

• Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server eases switch deployment.

• Automatic QoS (AutoQoS) simplifies QoS configuration in voice over IP (VoIP) networks by issuing interface and global switch commands to detect Cisco IP phones, classify traffic, and help enable egress queue configuration.

• Master configuration management helps ensure that all switches are automatically upgraded when the master switch receives a new software version. Automatic software version checking and updating help ensure that all stack members have the same software version.

• Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.

• Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports.

• Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel® groups or Gigabit EtherChannel groups to link to another switch, router, or server.

• Link Aggregation Control Protocol (LACP) allows the creation of Ethernet channeling with devices that conform to IEEE 802.3ad. This feature is similar to Cisco EtherChannel technology and PAgP.

• Automatic media-dependent interface crossover (MDIX) automatically adjusts transmit and receive pairs if an incorrect cable type (crossover or straight-through) is installed.

• Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links caused by incorrect fiber-optic wiring or port faults to be detected and disabled on fiber-optic interfaces.

High Availability

The Cisco Catalyst 3750-E Series increases availability for stackable switches. Each switch can operate both as master controller and as forwarding processor. Each switch in the stack can serve as a master, creating a 1:N availability scheme for network control. In the unlikely event of a single unit failure, all other units continue to forward traffic and maintain operation.

Other high-availability features include but are not limited to:

• Cross-Stack EtherChannel provides the ability to configure Cisco EtherChannel technology across different members of the stack for high resiliency.

• Flexlink provides link redundancy with convergence time less than 100 ms.

• IEEE 802.1s/w Rapid Spanning Tree Protocol (RSTP) and Multiple Spanning Tree Protocol (MSTP) provide rapid spanning-tree convergence independent of spanning-tree timers and also offers the benefit of Layer 2 load balancing and distributed processing. Stacked units behave as a single spanning-tree node.

• Per-VLAN Rapid Spanning Tree (PVRST+) allows rapid spanning-tree reconvergence on a per-VLAN spanning-tree basis, without requiring the implementation of spanning-tree instances.

• Cisco Hot Standby Router Protocol (HSRP) is supported to create redundant, failsafe routing topologies.

• Switch-port autorecovery (Errdisable) automatically attempts to reactivate a link that is disabled because of a network error.

High-Performance IP Routing

Cisco Express Forwarding hardware routing architecture delivers extremely high-performance IP routing in the Cisco Catalyst 3750-E Series Switches.

• IP unicast routing protocols (Static, Routing Information Protocol Version 1 [RIPv1], and RIPv2, RIPng, EIGRP stub) are supported for small-network routing applications.

• Advanced IP unicast routing protocols (OSPF, EIGRP, BGPv4 and IS-ISv4) are supported for load balancing and constructing scalable LANs. IPv6 routing (OSPFv3, EIGRPv6) is supported in hardware for maximum performance. The IP Services feature set is required.

• Equal-cost routing facilitates Layer 3 load balancing and redundancy across the stack.

• Policy-based routing (PBR) allows superior control by facilitating flow redirection regardless of the routing protocol configured. The IP Services feature set is required.

• HSRP provides dynamic load balancing and failover for routed links, up to 32 HSRP links supported per unit or stack.

• Protocol Independent Multicast (PIM) for IP multicast routing is supported, including PIM sparse mode (PIM-SM), PIM dense mode (PIM-DM), PIM sparse-dense mode and Source Specific Multicast (SSM). The IP Services feature set is required.

Superior Quality of Service

The Cisco Catalyst 3750-E Series offers Gigabit Ethernet speed with intelligent services that keep everything flowing smoothly, even at 10 times the normal network speed. Industry-leading mechanisms for marking, classification, and scheduling deliver superior performance for data, voice, and video traffic, all at wire speed.

Following are some of the QoS features supported in the Cisco Catalyst 3750-E Series Switches:

• Cross-stack QoS allows QoS to be configured across the entire stack.

• 802.1p class of service (CoS) and differentiated services code point (DSCP) field classification is provided, using marking and reclassification on a per-packet basis by source and destination IP address, MAC address, or Layer 4 TCP/UDP port number.

• Cisco control-plane and data-plane QoS ACLs on all ports help ensure proper marking on a per-packet basis.

• Eight egress queues per port help enable differentiated management of different traffic types across the stack. Four queues are user configurable and four are reserved for system use.

• Shaped Round Robin (SRR) scheduling helps ensure differential prioritization of packet flows by intelligently servicing the ingress queues and egress queues.

• Weighted Tail Drop (WTD) provides congestion avoidance at the ingress and egress queues before a disruption occurs.

• Strict priority queuing helps ensure that the highest-priority packets are serviced ahead of all other traffic.

• The Cisco committed information rate (CIR) function provides bandwidth in increments as low as 8 Kbps.

• Rate limiting is provided based on source and destination IP address, source and destination MAC address, Layer 4 TCP/UDP information, or any combination of these fields, using QoS ACLs (IP ACLs or MAC ACLs), class maps, and policy maps.

• Up to 64 aggregate or individual policers are available per Fast Ethernet or Gigabit Ethernet port.

Advanced Security

The Cisco Catalyst 3750-E Series supports a comprehensive set of security features for connectivity and access control, including ACLs, authentication, port-level security, and identity-based network services with 802.1x and extensions. This set of comprehensive features not only helps prevent external attacks, but defends the network against "man-in-the-middle" attacks, a primary concern in today's business environment. The switch also supports the Network Admission Control (NAC) security framework.

• Dynamic ARP Inspection (DAI) helps ensure user integrity by preventing malicious users from exploiting the insecure nature of the ARP protocol.

• DHCP Snooping prevents malicious users from spoofing a DHCP server and sending out bogus addresses. This feature is used by other primary security features to prevent a number of other attacks such as ARP poisoning.

• IP source guard prevents a malicious user from spoofing or taking over another user's IP address by creating a binding table between the client's IP and MAC address, port, and VLAN.

• Private VLANs restrict traffic between hosts in a common segment by segregating traffic at Layer 2, turning a broadcast segment into a nonbroadcast multi-access-like segment.

• Private VLAN Edge provides security and isolation between switch ports, which helps ensure that users cannot snoop on other users' traffic.

• Unicast RPF feature helps mitigate problems caused by the introduction of malformed or forged (spoofed) IP source addresses into a network by discarding IP packets that lack a verifiable IP source address.

• IEEE 802.1x allows dynamic, port-based security, providing user authentication.

• IEEE 802.1x with VLAN assignment allows a dynamic VLAN assignment for a specific user regardless of where the user is connected.

• IEEE 802.1x with voice VLAN permits an IP phone to access the voice VLAN irrespective of the authorized or unauthorized state of the port.

• IEEE 802.1x and port security are provided to authenticate the port and manage network access for all MAC addresses, including that of the client.

• IEEE 802.1x with an ACL assignment allows for specific identity-based security policies regardless of where the user is connected.

• IEEE 802.1x with guest VLAN allows guests without 802.1x clients to have limited network access on the guest VLAN.

• Web authentication for non-802.1x clients allows non-802.1x clients to use an SSL-based browser for authentication.

• Multi-Domain Authentication allows an IP phone and a PC to authenticate on the same switch port while placing them on appropriate Voice and Data VLAN.

• MAC Auth Bypass (MAB) for voice allows third-party IP phones without an 802.1x supplicant to get authenticated using the MAC address.

• Cisco security VLAN ACLs on all VLANs prevents unauthorized data flows from being bridged within VLANs.

• Cisco standard and extended IP security router ACLs define security policies on routed interfaces for control-plane and data-plane traffic. IPv6 ACLs can be applied to filter IPv6 traffic.

• Port-based ACLs for Layer 2 interfaces allow security policies to be applied on individual switch ports.

• Secure Shell (SSH) Protocol, Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) provide network security by encrypting administrator traffic during Telnet and SNMP sessions. SSH Protocol, Kerberos, and the cryptographic version of SNMPv3 require a special cryptographic software image because of U.S. export restrictions.

• Bidirectional data support on the Switched Port Analyzer (SPAN) port allows Cisco Intrusion Detection System (IDS) to take action when an intruder is detected.

• TACACS+ and RADIUS authentication facilitates centralized control of the switch and restricts unauthorized users from altering the configuration.

• MAC Address Notification allows administrators to be notified of users added to or removed from the network.

• Port Security secures the access to an access or trunk port based on MAC address.

• Multilevel security on console access prevents unauthorized users from altering the switch configuration.

• Bridge protocol data unit (BPDU) Guard shuts down Spanning Tree PortFast-enabled interfaces when BPDUs are received to avoid accidental topology loops.

• Spanning Tree Root Guard (STRG) prevents edge devices not in the network administrator's control from becoming Spanning Tree Protocol root nodes.

• IGMP filtering provides multicast authentication by filtering out nonsubscribers and limits the number of concurrent multicast streams available per port.

• Dynamic VLAN assignment is supported through implementation of VLAN Membership Policy Server client capability to provide flexibility in assigning ports to VLANs. Dynamic VLAN facilitates the fast assignment of IP addresses.

Intelligent Power over Ethernet (PoE) Management

The Cisco Catalyst 3750-E PoE models support Cisco IP phones and Cisco Aironet WLAN access points, as well as any IEEE 802.3af-compliant end device. The Cisco Catalyst 3750-E-48PD can support 48 simultaneous full-powered PoE ports at 15.4W with the 1150W power supply.

• Cisco Discovery Protocol version 2 (CDPv2) allows the Cisco Catalyst 3750-E Series Switch to negotiate a more granular power setting when connecting to a Cisco powered device such as IP phones or access points than what is provided by IEEE classification.

• Per Port power consumption command allows customers to specify maximum power setting on an individual port.

• Per Port PoE Power Sensing measures actual power being drawn, enabling more intelligent control of powered devices.

• The PoE MIB provides proactive visibility into power usage and allows customers to set different power level thresholds

Note:
Disclaimer: All power consumption numbers were measured under controlled laboratory conditions and are provided as an estimate.

The wattage rating on the power supply does not represent actual power draw. It indicates the maximum power draw possible by the power supply. This rating can be used for facility capacity planning. For PoE switches, cooling requirements are smaller than the actual power consumption as a significant portion of PoE loads are dissipated in the endpoints.

Non-PoE Power Consumption

100 Percent Throughput Switch Power Consumption

The numbers indicate the power consumed by a typical switch under normal conditions. Normal conditions signify a temperature of 25 degrees Celsius, atmospheric pressure in the range of 860 to 1060 mbar, and relative humidity from 30 to 75 percent. Typically such power draws are only seen when encountering a 100 percent traffic load made up entirely of 64-byte packets on the switch and the uplinks.

5 Percent Throughput Switch Power Consumption

The numbers indicate the power consumed by a typical switch under normal conditions. Normal conditions signify a temperature of 25 degrees Celsius, atmospheric pressure in the range of 860 to 1060 mbar, and relative humidity from 30 to 75 percent. The numbers below indicate a 5 percent traffic load on the switch and its uplinks.

PoE Power Consumption

100 Percent Throughput Switch Power Consumption (no PoE loads)

The numbers indicate the power consumed by a typical switch under normal conditions. Normal conditions signify a temperature of 25 degrees Celsius, atmospheric pressure in the range of 860 to 1060 mbar, and relative humidity from 30 to 75 percent. Typically such power draws are only seen when encountering a 100 percent traffic load made up entirely of 64-byte packets with no PoE loads on the switch and uplinks.

Measured 5 Percent Throughput Switch Power Consumption (no PoE loads)

The numbers indicate the power consumed by a typical switch under normal conditions. Normal conditions signify a temperature of 25 degrees Celsius, atmospheric pressure in the range of 860 to 1060 mbar and relative humidity from 30 to 75 percent. The numbers below indicate a 5 percent traffic load on the switch and its uplinks

100 Percent Throughput Switch Power Consumption (with maximum PoE loads)

The numbers indicate the power consumed by a typical system (the switch and the corresponding PoE loads) under normal conditions. Normal conditions signify a temperature of 25 degrees Celsius, atmospheric pressure in the range of 860 to 1060 mbar and relative humidity from 30 to 75 percent. Typically this power draw is realized when a switch is running 100 percent traffic load of 64 byte sized packets on all its ports and uplinks and also drawing 100 percent PoE load .

5 Percent Throughput Switch Power Consumption (with 50 percent PoE loads).

The numbers indicate the power consumed by a typical system (the switch and the corresponding PoE loads) under normal conditions. Normal conditions signify a temperature of 25 degrees Celsius, atmospheric pressure in the range of 860 to 1060 mbar and relative humidity from 30 to 75 percent. The numbers below indicate a 5 percent traffic load and 50 percent PoE load on the switch and its uplinks.
